Common Beer Off Flavours – Banana, Estery, Pear.
Off Flavour: Estery
Chemical Name: Isoamyl acetate
What to look for: This is quite distinctive and has an aroma of banana or pear. You will know it when you get it and is very common in wheat beers or big Belgians. Personally I like a bit of banana in my beer, but this is also a preference.

Common Beer Off Flavours – butterscotch, popcorn or butter.
Off Flavour: Diacetyl
Chemical Name: 2,3-butanedione
What to look for: Butter, oily, milky and feels a bit milky on the palate. This is quite easy to identify in a light lager but a darker beer, stout or ale at low levels can be a desirable flavour.
